A dental curable composition which comprises a radically polymerizable monomer component (A), a polymerizing catalyst (B) and an inorganic granular material (C), characterized in that:the radically polymerizable monomer component (A) contains a bifunctional monomer (A-1) represented by the following formula (α),        RP-SP1-RP     (α)where, Rp is a radically polymerizable group represented by CH2=C(R)-COO- or CH2=C(R)-CONH-, wherein R is a hydrogen atom or a hydrocarbon group having 1 to 3 carbon atoms, and SP1is a hydrocarbon group having 5 to 15 carbon atoms,and the content of the bifunctional monomer (A-1) in the radically polymerizable monomer component (A) is 5 to 40% by mass under a condition that the content of a diluting monomer (A-2) represented by the following formula (β),        RP-SP2-RP     (β)where, Rp is as defined in the above formula (α), and SP2is an aliphatic hydrocarbon group different from SP1, an oxygen-containing aliphatic hydrocarbon group having not less than 2 oxygen atoms, or an oxygen-containing aromatic hydrocarbon group having not less than 3 oxygen atoms,is zero or not more than 10% by mass.
